(173ab) A Study in Mexico for Advancing the Circular Economy and Sustainable Waste Management through Optimization of Waste-to-Energy Technologies

This study introduces an approach to sustainable waste management through Non-Linear Programming (NLP) for multi-objective and multi-period optimization, effectively integrating waste-to-energy technologies. The study examines the potential of Municipal Solid Waste (MSW) management as a significant energy reservoir by utilizing landfill gas recovery, biofuel production, and energy production. To comprehensively assess waste-to-energy options, the model incorporates four distinct technologies: anaerobic digestion, incineration, gasification, and pyrolysis. It carefully considers thermochemical, technical, economic, environmental, and social factors using rigorous non-linear functions, thereby offering a balanced strategy for waste management. Focusing on Mexico City, the research demonstrates the ability of the model to align economic goals with environmental sustainability. The methodology stands out for its capacity to balance the dual objectives of reducing environmental impact while enhancing economic benefits. By utilizing technologies like gasification and incineration, the model not only highlights the potential for significant emission reductions but also underscores the importance of energy production, contributing to sustainable energy goals. This work makes a significant contribution by providing a scalable and adaptable framework for sustainable waste management decision-making, advancing the field, and supporting urban sustainability initiatives.
